上海喆和定制銷售西門子電流互感器。主要技術(shù)要求額定容量：額定二次電流通過二次額定負(fù)荷時(shí)所消耗的視在功率。額定容量可以用視在功率，也可以用二次額定負(fù)荷阻抗Ω表示。一次額定電流：允許通過電流互感器一次繞組的用電負(fù)荷電流。用于電力系統(tǒng)的電流互感器一次額定電流為5～25000A，用于試驗(yàn)設(shè)備的精密電流互感器為～50000A。電流互感器可在一次額定電流下長期運(yùn)行，負(fù)荷電流超過額定電流值時(shí)叫做過負(fù)荷，電流互感器長期過負(fù)荷運(yùn)行，會燒壞繞組或減少使用壽命。二次額定電流：允許通過電流互感器二次繞組的一次感應(yīng)電流。額定電流比（變比）：一次額定電流與二次額定電流之比。額定電壓：一次繞組長期對地能夠承受的額定電壓（有效值以kV為單位），應(yīng)不低于所接線路的額定相電壓。電流互感器的額定電壓分為，3，6，10，35，110，220，330，500kV等幾種電壓等級。10%倍數(shù)：在指定的二次負(fù)荷和任意功率因數(shù)下，電流互感器的電流誤差為－10%時(shí)，一次電流對其額定值的倍數(shù)。10%倍數(shù)是與繼電保護(hù)有關(guān)的技術(shù)指標(biāo)。準(zhǔn)確度等級：表示互感器本身誤差（比差和角差）的等級。電流互感器的準(zhǔn)確度等級分為～1多種級別，與原來相比準(zhǔn)確度提高很大。上海優(yōu)惠特賣電流互感器全國發(fā)貨上海喆和定制銷售西門子APT電流互感器ALH-0.66.</p><div

為電流互感器的比差。當(dāng)KNI2>I1時(shí)，比差為正，反之為負(fù)。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66 60*50II電流互感器.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
